chore: add Catalina native dependencies guide (#3180)

With the Catalina macOS upgrade, several users started to face issues when
trying to install native dependencies. There's a guide on `node-gyp` repository
with possible workarounds for the issue, but the guide is hard to find (if you
search for `gyp canalina issues` and variants on Google, you won't get the
guide on first page, and if you search for the error `gyp: No Xcode or CLT
version detected!`, the issue on node-gyp where the problem is discussed and
the guide is linked does not show in the first few results. Adding the guide to
our Guides page might make discoverability better in the future.
